What kind of stainless steel mesh filter are there? What are the points for attention in maintenance?

Now the application of mesh filter is more and more frequent, the core of the device is mesh stainless steel filter, it is the liquid particles automatically filter under certain conditions to remove the separation filter device. Compared with the traditional filter device, the self-cleaning filter device has the following characteristics: high degree of automation, low pressure loss, and no need for manual removal of filter residue. In the time of cleaning can also be uninterrupted water supply, fully ensure the efficiency of the work. At present, the self-cleaning filter device is mainly suitable for separation and filtration in industry, agriculture, municipal and seawater desalination processes. Speaking of its origin, it is mainly due to the continuous development of society, and the progress in productivity can not avoid the emergence of more and more factories. Many factories produce sewage when they produce, so the sewage treatment industry is also developing very fast, in order to meet the speed of processing, but also to maintain efficiency, so the screen-type stainless steel filter should be born.

First, I will introduce the filtration process: the preferential step is to enter the sewage through the inlet of the filtration device, and then flow through the filter screen from the inside to the outside, which impurities larger than the mesh are intercepted, and the accumulation of excessive words in the inner surface of the filter to form cake, cake formation, can also be able to capture some of the smaller impurities in the water. Secondly, I will introduce the self-cleaning process: under the control of the system, the dirt sucker will be driven by a two-way motor with a screw device, which will then be driven at a fixed speed for the spiral-type movement, this also formed a number of suction nozzle can suck the entire filter surface, and the whole process takes about half a minute. It is worth mentioning that the whole anti-cleaning process, the system is continuous flow to understand. Moreover, the whole operation of all filter devices is controlled by the program controller, which ensures the continuous and efficient operation of the system. The pressure difference switch continuously detects the pressure difference between inside and outside the filter screen. When the pressure difference reaches the preset value, a signal is transmitted to the control box to start the cleaning cycle. Because the cleaning mechanism of the filter device is a spiral up and down movement of the dirt absorber, and is hollow structure. So when the drain valve is opened, the pressure difference between the water pressure inside the filter and the outside atmosphere causes the suction pipe to generate strong suction, water flow from the filter screen to the inside reverse high-speed flow will be washed down the impurities into the sewage suction through the discharge valve discharge.
